RESUMEN
Background: No effective medication is available for symptomatic bradyarrhythmia, particularly in low socioeconomic status (SES) population. Objective: To explore the safety and efficacy of Yuanjiang decoction, a traditional Chinese medicinal prescription, for symptomatic bradyarrhythmia on a compassionate-use basis. Methods: This compassionate-use study was conducted in Beijing, China between January 2019 and January 2020. Eligible participants were recruited and treated with Yuanjiang decoction (composed of 6 Chinese herbal medicines), 200 ml twice daily for 16 weeks. Analyses were done with the intention-to-treat (ITT) approach. The primary outcome measure was the proportion of participants who achieved a favorable treatment outcome at 16 weeks. Results: As of January 2020, 184 patients were included. After 16-weeks treatment, 12 participants were lost to contact while 21 participants were terminated from this study, with a drop-out rate of 17.93%. The most common treatment-related adverse events were xerostomia (6.52%), constipation (6.45%) and sleepiness (3.26%). The proportion of participants with favorable treatment outcome was 65.22% at 4 weeks, 59.78% at 8 weeks (OR: 1.11, 95% CI: 0.71-1.73), 61.41% at 12 weeks (OR: 1.16, 95% CI: 0.92-1.45) and 60.87% at 16 weeks (OR: 1.15, 95% CI: 0.98-1.35). In the multifactor regression analysis, the favorable treatment outcome at 16 weeks was significantly associated with completing at least 8 weeks treatment (OR: 2.053, 95% CI: 1.064-3.560), while unfavorable treatment outcome was significantly associated with an atrioventricular block (OR: 0.255, 95% CI: 0.083-0.784), current smoking (OR: 0.343, 95% CI: 0.027-0.487), and syncope in the month before treatment (OR: 0.321, 95%CI: 0.114-0.904). Conclusion: This compassionate-use study showed encouraging outcomes of treatment with Yuanjiang decoction, without serious adverse events. This study identified several key factors that may affect outcomes. These findings helped inform the design and assess the feasibility of a large-scale randomized clinical trial.
RESUMEN
<p><b>OBJECTIVE</b>To evaluate the quality and consistency of recommendations in the clinical practice guidelines (CPGs) for hypertension in Chinese medicine (CM).</p><p><b>METHODS</b>CM CPGs were identified from 5 electronic databases and hand searches through related handbooks published from January 1990 to December 2013. Three reviewers independently appraised the CPGs based on the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument, and compared the CPGs' recommendations on CM syndrome pattern classification and treatment.</p><p><b>RESULTS</b>Five CM CPGs for hypertension were included. The quality score of the evidence-based (EB) guideline was higher than those of the consensus-based with no explicit consideration of evidence-based (CB-EB) and the consensus-based (CB) guidelines. Three out of five patterns in the CPGs were recommended by the EB guideline. Tianma Gouteng Formula () in the EB guideline was recommended mostly for hypertension patients with pattern of ascendant hyperactivity of Gan (Liver)-yang and pattern of yin deficiency with yang hyperactivity in the CPGs. Acupuncture and massage were recommended for Grade I and Grade II hypertension with severe symptoms weakening the quality of life in the EB guideline. For Grade I and Grade II hypertension, CM could be used alone, while for Grade III hypertension, they should be used in combination with Western medicines.</p><p><b>CONCLUSION</b>The quality of EB guideline was higher than those of CB and CB-EB CPGs in CM for hypertension and CM should be prescribed alone or combined with Western medicines based on the grade of hypertension.</p>

Previous studies have shown that paeonol can antagonize acute myocardial ischemia and infarction in rat. This study further researched the effects of paeonol on blood pressure and blood flow in the artery of spontaneously hypertensive rats and its mechanisms related on vasomotion. Firstly, thirty spontaneously hypertensive rats were randomly divided into spontaneously hypertensive control group and paeonol-treating groups of high dose and low dose, and also, the other ten Wistar rats as healthy control group. Before and after the intraduodenal administration of the drug, arterial blood pressure was measured by carotid artery and blood flow through the renal artery and carotid artery in vivo were measured by animal flowmeter. The same volume of solvent was given to the spontaneously hypertensive control group and the healthy control group, and the other operations were same. In order to further study the effect of paeonol on vasomotor function, the superior mesenteric artery, renal artery and coronary artery of the spontaneously hypertensive rat were removed and separated, precontracted by a certain concentration of potassium chloride (KCl) and 5-serotonin (5-HT) respectively, and dilatory responses were assessed by cumulative addition of paeonol. Results showed that after duodenal one-time delivery of paeonol, the blood pressure significantly lowered, the renal arterial blood flow and the carotid arterial blood flow significantly increased in spontaneously hypertensive rat. And also, paeonol relaxed the mesenteric artery, renal artery and the coronary artery of spontaneously hypertensive rat in a concentration-dependent manner. These results indicated that the effect of paeonol on decreasing arterial blood pressure and increasing the arterial blood flow was related to its vasodilative effect.

Huangqi powder injection's positive rate of skin-test was 12.3%. Qingkailing powder injection was 3.0%. Qingkailing injection was 7.6%. Shuanghuanglian injection was 6.3%. Penicillin's rate of allergic reactions was 0.7%-10%. Different form of a drug (power or injection) and different drug consistency could influence the positive rate of skin-test. We don't use drug in positive group, and we use drug in negative group. Some trial subjects still happened allergic reactions in negative group of skin-test. In negative group of skin-test, Huangqi power injection's rate of allergic reactions was 2.1%. Qingkailing injection was 0.4%. Shuanghuanglian injection was 0.9%-2.6%. Shuanghuanglian injection's rate of allergic reactions was 8.6% in all subjects (31/360 include the subjects with positive skin-test and allergic reactions). Qingkailing powder injection's rate of allergic reactions was 4.5% (6/132). Qingkailing injection' s rate of allergic reactions was 9.1% (12/132). Huangqi power injection's rate of allergic reactions was 15.4% (62/402). The total rate of allergic reactions was 10.8%. The main appearance of Penicillin's skin-test was welling under skin, and with some blush. But the main appearance of traditional Chinese medicine skin-test was blush, and with a little welling under skin. Skin-test can reduce the allergic reactions of Qingkailing powder injection, Shuanghuangiian injection, Huangqi power injection. It can be the one measure of reducing adverse reactions.
